Member Function Documentation

void ns3::Application::DoDispose ( void )

protectedvirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

Reimplemented in ns3::UdpEchoClient, ns3::OnOffApplication, ns3::UdpTraceClient, ns3::Ping6, ns3::PacketSink, ns3::Radvd, ns3::EpsBearerTagUdpClient, ns3::BulkSendApplication, ns3::UdpServer, ns3::UdpClient, ns3::EpcEnbApplication, ns3::EpcSgwPgwApplication, and ns3::UdpEchoServer.

References ns3::EventId::Cancel(), m_node, m_startEvent, m_stopEvent, and NS_LOG_FUNCTION.

Here is the call graph for this function:

void ns3::Application::DoInitialize ( void )

protectedvirtual

This method is called only once by Object::Initialize. If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject and AggregateObject from within this method.

Reimplemented from ns3::Object.

Returns: the Node to which this Application object is attached.

Parameters

node	the node to which this Application object is attached.

Here is the caller graph for this function:

void ns3::Application::SetStartTime ( Time start )

Specify application start time.

Parameters

start Start time for this application, relative to the current simulation time.

Applications start at various times in the simulation scenario. The Start method specifies when the application should be started. The application subclasses should override the private "StartApplication" method defined below, which is called at the time specified, to cause the application to begin.

Here is the call graph for this function:

Here is the caller graph for this function:

void ns3::Application::SetStopTime ( Time stop )

Specify application stop time.

Parameters

stop	Stop time for this application, relative to the current simulation time.

Once an application has started, it is sometimes useful to stop the application. The Stop method specifies when an application is to stop. The application subclasses should override the private StopApplication method, to be notified when that time has come.
